It is currently unknown what species Washington State coprolite from the Wilkes Formation is from, but the most accepted theory is that they are coprolites and intestinal casts from Predatory Sea Worms! They can range vastly in size size and shape, with most having a pretty interesting appearance to say the least! For a long time the coprolite from this formation was thought to be pseudo-coprolite, a form of material that only resembled coprolite. However, recent studies have shown that it does in fact contain organic material, and is indeed a form of coprolite. Either way, they are totally awesome, and would make a great investment or collectors batch!
